Hmm ... poking around, I see several other places that aren't checking the result of ecpg_get_connection. Shouldn't we tighten them all?

I agree. I’ve reviewed all occurrences of ecpg_get_connection() and noted that, in most instances, it is followed by ecpg_init(), which validates the connection and returns immediately if the connection is NULL.
In a few cases, the caller had already validated the connection. However, I identified an additional case that lacked this check, so I have revised the patch to include the missing validation.
